Many end users have complained that the original nuts that come with the URX rail easily strip or are damaged during barrel changes. These barrel nuts are intended as tool steel replacements to the factory aluminum barrel nuts to provide increased strength and ease of serviceability. They are designed to work with our aftermarket wrench as well as a factory unit and are compatible with the URX II, 3.0, and 3.1.

Things went well with testing the fit up for the threads, so production has commenced. All these barrel nuts are done with OP 1 on the lathe. The next step is cutting the teeth.
